FIG. 1A is a front view showing a packaging container according to the present embodiment, and FIG. 2B is a sectional view taken along the line bb ′. FIG. 2 is a sectional view showing an image forming area in the packaging container according to the present embodiment. FIG. 1 is a cross-sectional view illustrating a method for manufacturing a packaging container according to the present embodiment. In the figure, reference numeral 1 denotes a packaging container.

  The packaging container 1 which concerns on this embodiment is a refill container which consists of a laminated body which has at least the base material 11 and the sealant layer 12, as shown to Fig.1 (a) (b), Comprising: Two laminated bodies are comprised. The main body surface laminate 2 and the main body back laminate 3 are formed with the sealant layer inside, and another laminate is folded with the sealant layer outside to form the bottom tape 4, and the main body surface laminate 2 and the main body back laminate. A standing pouch is formed by inserting between the bodies 3 and sealing the periphery. The standing pouch-shaped container can easily be a large-capacity container because the bottom tape 4 spreads.

As shown in FIG. 3, a vapor deposition layer 11b is formed by depositing a metal such as aluminum or tin or a metal oxide such as silica or alumina on the transparent sheet 11a. In addition, the metal foil film 11b can be adhered to the transparent sheet 11a, and further, a printed layer or an adhesive layer can be included as the laminates 2, 3, and 4.

  As shown in FIG. 1B, side seal portions (seal portions) 22 are provided on both sides of the main body surface laminate 2 and the main body back surface laminate 3, and the main body surface laminate 2 and the bottom tape 4 Also, a bottom seal portion (seal portion) 23 is provided below the main body back surface laminate 3 and the bottom tape 4.

In the upper part of the main body surface laminate 2 and the main body back laminate 3, a filling nozzle 41 and a pouring nozzle 32 for pouring the contents are formed together with the pouring nozzle seal portion 24. The tip of the dispensing nozzle 32 is sealed by the dispensing nozzle tip seal portion 24, and forms a spout by being cut off from the opening notch 35. A plurality of laser cut lines that are parallel to the planned opening line may be provided in the vicinity of the dispensing nozzle 32 and the opening notch 35.

The main body surface laminate 2 of the packaging container 1 according to the present embodiment is provided with an image forming area 5 and a printing area 7 as shown in FIG. Ink layer (printed area) 7 with different in-key color in the region of each 7a to 7e, is intended to form a multicolored pattern as a whole. When performing these printings, an anchor coat that improves ink adhesion may be interposed between the ink layer 7 of the image and the surface of the substrate 11.
The image forming area 5 can also be formed on the surface of the main body back surface laminate 3.

It is provided in a portion that is not sealed in the vertical direction, and a very fine line-shaped uneven pattern group is formed on the main body surface laminate 2 and the main body back laminate 3.
The line-shaped concavo-convex pattern group was formed by forming an ink layer 7 by using a press plate in which a fine line-shaped concavo-convex pattern group was formed by changing its direction little by little to form a required emboss pattern for identification for preventing counterfeiting. It is produced by pressing on the surface of the substrate 11.

In such an image forming region 5, the direction of the line-shaped uneven pattern group changes little by little, so the reflection direction of the light reflected by each line-like uneven pattern group on the surface changes little by little, Depending on the viewing direction and angle, the brightness and brightness of the gloss change dynamically. For this reason, a very precise visual effect is exhibited. In this way, changing the viewing angle changes the characters and patterns minutely as “changing” technology.
For example, as shown in FIG. 2, an image indicated by “T” or “P” can be visually recognized depending on the viewing angle, and the visually recognizable image changes.

Further, the image forming area 5 having this effect, manufacture very difficult embossed pattern formed on the press plate, also for the registration fit is very difficult, in key is previously formed on the substrate 11 layer 7 It is difficult for a third party to forge when a position is set with a pattern consisting of

  As the laminates 2, 3, and 4, laminates usually used for soft packaging bags can be used. As the substrate 11, paper, metal foil, or synthetic resin film composed of one layer or several layers is used. For example, the low-density polyethylene resin (LDPE), the high-density polyethylene resin (HDPE), the linear low-density polyethylene resin (LLDPE), the polypropylene resin (PP), and the polyolefin-based elastomer that can be used as the transparent sheet 11a. Polyolefin resins such as polyethylene terephthalate resin (PET), polybutylene terephthalate resin (PBT), polyester resins such as polyethylene naphthalate resin (PEN), cellulosic resins such as cellophane and cellulose triacetate (TAC), polymethyl Methacrylate (PMMA) resin, ethylene-vinyl acetate copolymer resin (EVA), ionomer resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene resin (PS), polyvinyl chloride Resin (PVC), polyvinylidene chloride resin (PVDC), polycarbonate resin (PC), fluorine-based resin, synthetic resin films and paper, such as urethane resin, a metal foil or the like alone or be used in combination.

  As the sealant layer 12, a polyolefin resin is generally used. Specifically, a low density polyethylene resin, a medium density polyethylene resin, a linear low density polyethylene resin, an ethylene / vinyl acetate copolymer, an ethylene / α Ethylene resins such as olefin copolymers, polypropylene resins such as homopolypropylene resins, propylene / ethylene random copolymers, propylene / ethylene block copolymers, and propylene / α olefin copolymers are used. In addition, a multilayer film in which these resins are combined may be used.

  Specific structural examples of the laminates 2, 3 and 4 include PET / printing layer / adhesive layer / stretched polyamide resin film (hereinafter abbreviated as ONY) / adhesive layer / LLDPE film, ONY / Examples thereof include adhesive layer / LLDPE, ONY / adhesive layer / ONY / adhesive layer / LLDPE, paper / LDPE / aluminum foil / LDPE, paper / LDPE, and the like.

  Hereinafter, the manufacturing method of the packaging container in this embodiment is demonstrated.

  When manufacturing the packaging container 1 in this embodiment, as shown to Fig.3 (a), the base material 11 used as said laminated body 2,3,4 is first prepared. The base material 11 is a transparent sheet 11a provided with a vapor deposition layer 11b such as aluminum.

  Next, as shown in FIG. 3B, the sealant layer 12 is laminated on the base material 11.

Then, as shown in FIG. 3 (c), to form a predetermined in-key layer 7 was printed on a substrate 11 surface.

  Next, as shown in FIG. 3 (d), the substrate is formed from the top of the ink layer 7 of the image by a press plate in which a fine line-shaped uneven pattern group is formed in a required emboss pattern by changing its direction little by little. By pressing the surface 11, the image forming region 5 composed of a very fine line-shaped uneven pattern group is formed on the surface of the substrate 11.

  In this line-shaped concavo-convex pattern group, for example, the groove pitch width is 60 to 90 μm, the concavo-convex depth is 10 to 20 μm, and the direction and pitch width of the fine concavo-convex pattern group according to the pixel of the image And depth can be changed little by little.

  In the present embodiment, the direction of the line-shaped concavo-convex pattern group and the pitch and depth of the concavo-convex are changed slightly for each of the ink regions 7a to 7e forming the pixels. That is, the line-shaped uneven pattern groups corresponding to adjacent regions such as the region 7a and the region 7b are different from each other.

The processing of the line-like uneven pattern as the image forming region 5 is performed by pressing the base material 11 to be the main body surface laminate 2 or the main body back surface laminate 3 with a press plate on which a required emboss pattern is formed as in the conventional case. Can be done.

In the image forming region 5 formed in this way, the vapor deposition layer 11b such as aluminum and the transparent sheet 11a are simultaneously processed into a line-like uneven pattern, so that the image pattern is divided into a plurality of types depending on the viewing angle and direction. Set to change. Furthermore, since the deposition layer 11b of aluminum or the like as a metallic luster surface is formed on the inside, is protected from the outside by a transparent sheet 11a, with its gloss is not lost forever, incidence of the deposition layer 11b of aluminum or the like Since the light and the reflected light pass through the transparent sheet 11a, the effect of maintaining visual recognition of the image can be exhibited even when the surfaces of the laminates 2 and 3 are damaged.

Next, the main body front surface laminate 2 and the main body back surface laminate 3 in which the image forming region 5 is formed in this way are placed with the bottom tape 4 sandwiched between the sealant layers 12 facing each other, and the peripheral edges of these laminates 2, 3, 4 are Sealing is performed to form the sealing portions 22, 23, and 24, whereby the packaging container 1 having a standing pouch shape is obtained.

In the packaging container 1 of the present embodiment, the formation of the image forming region 5 makes it impossible for a third party to manufacture, and can exhibit an anti-counterfeit effect. Furthermore, it is possible to easily apply a concavo-convex pattern to a complex information or an image of a person / landscape on the base material 11 to make it possible to produce fine and diverse expressions and to keep an extremely brilliant image forever. be able to.
Further, by forming the image forming region 5 integrally with the packaging container 1, forgery without increasing the number of manufacturing steps compared to a means for performing authentication with a seal or the like or a means having a laser irradiation process for authentication. The prevention effect can be improved.

  In addition, when using paper as the base material 11, high-quality paper, piece art paper, coated paper, cast coated paper, imitation paper, or the like can be used as the paper. When a laminate including a layer made of paper is used, cracking may occur in the paper due to deep embossing. Therefore, when used in the packaging container of this embodiment, as a convex emboss and a concave emboss, By adopting the embossed shape, a laminate using paper can be used stably. It is also effective to use paper from the viewpoint of environmental considerations.

Compared with the case where it does, it becomes possible to reduce the number of manufacturing processes, to reduce manufacturing time, and to reduce manufacturing cost.

  Furthermore, in order to form the image forming region 5 in the seal portion 22 having a thickness larger than that of the single laminates 2, 3, and 4, the thickness capable of forming a line-shaped uneven pattern in the image forming region 5 is increased. In this way, it is possible to provide a more complicated structure with a higher degree of freedom in the formation of images, characters, and the like for display in the image forming area 5. Thereby, the forgery prevention effect can be further enhanced.

Hereinafter, 3rd Embodiment of the packaging container which concerns on this invention is described based on drawing.
FIG. 5 is a front view showing the packaging container in the present embodiment.
This embodiment is different from the first embodiment described above in that the vapor deposition layer 11c is formed only in the portion where the image forming region 5 is formed and the embossed portion 38, and other than this, it corresponds. Constituent elements are denoted by the same reference numerals and description thereof is omitted.

In the packaging container 1 of this embodiment, as shown in FIG. 5, the vapor deposition layer 11c is formed only in the part containing the image formation area 5, and other laminated bodies 2, 3, and 4 are transparent sheets.

Further, printing may not be performed in the image forming area 5 and the ink layer 7 may not be formed so as to overlap.

  In the above-described embodiment, the vapor deposition layer 11b or the vapor deposition layer 11c is used. However, a packaging container in which the image forming region 5 is formed can be formed using a laminate without the vapor deposition layer. Also in this case, a configuration in which the ink layer 7 overlaps the image forming region 5 and a configuration in which the ink layer 7 does not overlap the image forming region 5 are possible. Further, the ink layer 7 can be formed on a surface other than the surface of the substrate 11.

  Further, as the image forming area 5, a very fine line-shaped uneven pattern group is formed on the base material 11 from above the ink layer 7 of the image, and the direction of the line-shaped uneven pattern group is gradually changed. Therefore, the reflection direction of the light reflected by each line-shaped concavo-convex pattern group on the surface changes variously, depending on the viewing direction and angle, the brightness and brightness of the metallic luster, and when overlaid on the printed image, in addition to this The color of the ink may be dynamically changed to exhibit a visual effect called an extremely brilliant opal effect.
